Transient X-Ray Irradiation of High Transition Temperature Superconducting Material

Abstract

This report describes transient radiation studies performed on high critical temperature (Tc) superconductors by Weapons Laboratory (WL) personnel in the Wl Flash X-ray Facility. The objective was to detect any transient effects on the superconductivity of high Tc material during irradiation by an X- ray pulse. Each sample of high Tc material was cooled to a temperature below its Tc and then irradiated with a 20-ns pulse from a Febetron 705 flash x-ray machine. Each pulse delivered 85 rad(Si) to the sample. The samples were current biased and their conductivity measured during irradiation. Within instrumentation limits, measurements made on thin film high Tc material revealed no changes in conductivity during or after irradiation. (rh)
